My mother has the Mobile Help system and it is wonderful!!! She has the necklace alarm for when she is working outside or around the house as well as the GPS monitoring system. The company responds quickly to alarms. Just a couple months ago, she accidentally set the alarm off while working in the garden and was pleasantly surprised to have 2 visitors from the company arrive at her home (when she failed to answer her cell phone). It is quite a blessing to have this bc it gives her the confidence to live and explore and do what she wants to do without being fearful of an accident. God Bless you all!!
